On the periodic table, there are eleven elements that are gases at room temperature. These are: Hydrogen (H), Helium (He), Nitrogen (N), Oxygen (O), Fluorine (F), Chlorine (Cl), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).

One could not count the number of gaseous compounds formed by chemical reactions, and since new compounds are being discovered every day, it is impossible to know how many gases there are in the world.
